Which PyS60: launchpad or maemo?

I dabbled in PyS60 development a few years ago and now I'm getting back into it. To be on the safe side I'm unistalling and reinstalling everything.

There now seem to be two PyS60 distributions: this "Community Edition" on launchpad, and a pys60 project on the Maemo garage [1]. The version numbers are different, so is the lanchpad 1.8.1211 "stable" and the maemo 1.9.7 "development", or are the two projects forks, or unrelated? And in any case, which should I install on my phone, and/or into the emulator on my desktop?

Sorry if this is a stupid question but I've been unable to find out any other way.
